如何获取表格行后的空间（加载了 tabularx）？

我尝试使用\\[\bigskipamount]在表格行之间创建空白，但tabularx加载包后，空白没有出现。以下是 MWE：

\documentclass{article}
\usepackage{tabularx} % to get expected behavior, comment this out
\begin{document}
\thispagestyle{empty}
\noindent
\begin{tabular}{p{\linewidth}}
The machine has just finished evaluating an expression to
produce value~$v$; it is about to plug~$v$ into the hole in the top
frame of stack~$S$.
The~machine's next transition is determined by the syntactic form
of~the stack~$S$---usually by the form of the
topmost~frame---and possibly also by a property of~$v$.
\\[\bigskipamount]
The machine has just finished evaluating an expression to
produce value~$v$; it is about to plug~$v$ into the hole in the top
frame of stack~$S$.
The~machine's next transition is determined by the syntactic form
of~the stack~$S$---usually by the form of the
topmost~frame---and possibly also by a property of~$v$.
\\
\end{tabular}

\end{document}

结果如下：

意外行为---没有垂直空间

如果我注释掉\usepackage{tabularx}，我就会得到我希望的结果：

预期行为

我需要做什么才能获得我想要的装载空间tabularx？

答案1

在这种情况下，预期的行为是不会获得任何额外的空间，因为p列深度已经大于使用可选参数添加的额外深度。

tabularx除了加载array修复此错误的包之外，此更改与其他更改无关。

如果添加额外的列（使这里的年龄过满，但忽略这一点），则会更清楚

\documentclass{article}
%\usepackage{array} % to get same behaviour with or without this 
\begin{document}
\thispagestyle{empty}
\noindent
\begin{tabular}{p{\linewidth}c}
The machine has just finished evaluating an expression to
produce value~$v$; it is about to plug~$v$ into the hole in the top
frame of stack~$S$.
The~machine's next transition is determined by the syntactic form
of~the stack~$S$---usually by the form of the
topmost~frame---and possibly also by a property of~$v$.
&zzz\\[\bigskipamount]

在这里，您可以看到无论有没有array深支柱产生的行为都是相同的，因为\\[\bigskipamount]它附着在 c 柱的基线，所以由于p柱的深度更大，所以没有影响。

可选参数的行为\\[..]确实应该取决于整行，而不应仅受最后一列的影响。array包实现确保了这一点。

要添加更多空间，请为可选参数添加更大的长度，或\bigskip在条目末尾添加p或使用\\\noalign{\bigskip} （booktabs 包有一些间距命令来隐藏\noalign原始命令，但相当于这个）
